The adapter has not proven after two holidays. Overall, it is very large and unwieldy, turning to go to the different ports, works relatively heavy. The biggest problem, however, unfortunately, that in the adapter itself only the large circular device connector fit, unfortunately the narrow Connectors do not fit due to the contacts of the earth, because the insertion is blocked in the adapter thereby. But as you unfortunately can not guarantee to have only devices with circular device connectors on holiday here, the adapter for me is not to use. Too Bad.
